Abstract (en)
[origin: WO03056715A1] Method to control the output signal of signal transmitter in a data system sending data in low voltage net in order to keep the utput signal voltage (UL) constant, when output signal (UL) is taken over coupling unit (50) to the network, whereby the data transmission includes a signal amplifier (20), a signal filter (40), a coupling unit (50) for signal coupling to the network and a source (10) of signal amplifier operating voltage (US). In connection with the signal amplifier (20) there is a signal clipper (30) or a function to clip output signal (UOUT) of signal amplifier (20) and/or to clip or distort the input signal approaching signal amplifier (20) and clipping or distortion being directly or indirectly dependent on the output voltage (UL) of the signal to be sent to the network or on the output current (IOUT) from signal amplifier (20).
